Hello,
 I have a user control form built using Visual Studio 2005 on vb.net with a JavaScript call to calculate total.
Below, please find my code:
-----------
 Protected Sub RSVPForm1_CalculateTotalEvent(ByVal e As HGACServerControls.CalculateTotalEventArgs)
        If (IsPostBack) Then
           
            Dim totalBox As HiddenField
                
           
            'find the control
            totalBox = RSVPForm1.FindControl("hdnTotal")
                       
            'Lets go ahead and throw an exception if the we could not find our total
            'If (totalBox Is Nothing) Then
            'Throw New Exception("Could not get total")
            'End If

            Try
                e.Total = CDec(Page.Request.Form(totalBox.UniqueID))
            Catch
                ' If Conversion does not work set to zero
                e.Total = New Decimal(0)
            End Try
                   
        End If
    End Sub
   
    Protected Sub RSVPForm1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim hdnTotal As HiddenField
       
        hdnTotal = RSVPForm1.FindControl("hdnTotal")
       
       
       
        If Not (hdnTotal Is Nothing) Then
            Page.ClientScript.RegisterClientScriptBlock(Page.GetType(), "hdnTotalIdScript", "var hdnTotalId = '" + hdnTotal.ClientID + "';", True)
        End If
       
       
    End Sub
</script>
<script language="JavaScript" type="text/javascript">

function RegTotal()
{
form = document.forms[0];


if ((form.Total.value == "0") || (form.Total.value.length == 0))
      {      
      alert("Please enter a sponsorship amount before submitting the form.");
      }

var obj = document.getElementById(hdnTotalId);


obj.value = form.Total.value;

}
</script>
-----------
The call to this JavaScript is as follows:
----------
<tr>
     
      <td style="background-color:#FFFFBF"><strong><span style="color:Crimson">Amount sponsor: $ </span></strong></td>
      <td style="background-color:#FFFFBF"><INPUT TYPE=TEXT NAME="Total" SIZE=12 onChange="RegTotal();" value="0" style="background-color:#FFFFBF;font-weight:bold;" />      
      <asp:HiddenField ID="hdnTotal"  runat="server"/></td>  
   
</tr>
-------
I am attempting to duplicate the JavaScript function using VB.NET.  For example, I am trying to write a sub in vb.net specifically to capture the call this code:
-----------
var obj = document.getElementById(hdnTotalId);
obj.value = form.Total.value;
-------
of interest, is the call to "hdnTotalID".

ANY help would be greatly appreciated.

On page_load when you need it just write:
hdnTotal.Value
 to get he same value assigned by JS in your page

mas_oz2003,

Thank you for the quick reply.
When i implemented your suggestion by entereing "hdnTotal.Value" at Page_Load, VS is indicating the folllowing: "name 'hdnTotal is not declared"
Below, please find my code:
-------
<%@ Control Language="VB" ClassName="RSVP_FreshAirFriday_PromoCode"  %>

<script runat="server">
 
   
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        'If (Not IsPostBack) Then
        'Dim lb As Label
           
        'lb = RSVPForm1.FindControl("OrderTotalAmount2")
           
        ' dd.Items.Add(New ListItem("Home Rule", "Home Rule"))
        ' dd.Items.Add(New ListItem("General Law", "General Law"))
         
        'End If
       
        hdnTotal.Value()

    End Sub
 
    Protected Sub RSVPForm1_CalculateTotalEvent(ByVal e As HGACServerControls.CalculateTotalEventArgs)
        If (IsPostBack) Then
           
            Dim totalBox As HiddenField
                
           
            'find the control
            totalBox = RSVPForm1.FindControl("hdnTotal")
                       
            'Lets go ahead and throw an exception if the we could not find our total
            'If (totalBox Is Nothing) Then
            'Throw New Exception("Could not get total")
            'End If

            Try
                e.Total = CDec(Page.Request.Form(totalBox.UniqueID))
            Catch
                ' If Conversion does not work set to zero
                e.Total = New Decimal(0)
            End Try
                   
        End If
    End Sub
   
    Protected Sub RSVPForm1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim hdnTotal As HiddenField
       
        hdnTotal = RSVPForm1.FindControl("hdnTotal")
       
       
       
        If Not (hdnTotal Is Nothing) Then
            Page.ClientScript.RegisterClientScriptBlock(Page.GetType(), "hdnTotalIdScript", "var hdnTotalId = '" + hdnTotal.ClientID + "';", True)
        End If
       
       
    End Sub
</script>
<script language="JavaScript" type="text/javascript">

function RegTotal()
{
form = document.forms[0];


if ((form.Total.value == "0") || (form.Total.value.length == 0))
      {      
      alert("Please enter a sponsorship amount before submitting the form.");
      }

var obj = document.getElementById(hdnTotalId);


obj.value = form.Total.value;

}
</script>
<br />
-----------
The call to the "RegTotal" javascript is as follows:
-------
 <tr>
     
      <td style="background-color:#FFFFBF"><strong><span style="color:Crimson">Amount sponsor: $ </span></strong></td>
      <td style="background-color:#FFFFBF"><INPUT TYPE=TEXT NAME="Total" SIZE=12 onChange="RegTotal();" value="0" style="background-color:#FFFFBF;font-weight:bold;" />      
      <asp:HiddenField ID="hdnTotal"  runat="server"/></td>  
   
</tr>
 ------
What I'm ttrying to do is to write a sub in response to a button_click event that would provide the same results as the JavaScript script "RegTotal".  
For example, the RegTotal javascript returns the following:
--------
var obj = document.getElementById(hdnTotalId);

obj.value = form.Total.value;
-----
and I receive in my email the value of  the amount the user entered into the field
"><INPUT TYPE=TEXT NAME="Total" SIZE=12 onChange="RegTotal();" value="0" style="background-color:#FFFFBF;font-weight:bold;" />      
      <asp:HiddenField ID="hdnTotal"  runat="server"/>
-------

THe sub I'm attempting to write would return the value entered into hdnTotal as a numeric value. I think that in the javascript above, t his is called from the value "(hdnTotalId)"

ANY help in writing this sub would be greatly appreciated.

Strange, because you are declaring it for server usage in the markup as follows:
<asp:HiddenField ID="hdnTotal"  runat="server"/></
I notice that in your code you already have a Load method, use it in this way:(Note : Delete Page_Load)
    Protected Sub RSVPForm1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim hdnTotal As HiddenField
       
        hdnTotal = RSVPForm1.FindControl("hdnTotal")
        'Use hdnTotal, you can include in the if below for extra check
        Dim s As String = hdnTotal.Value.ToString()
        If Not (hdnTotal Is Nothing) Then
            Page.ClientScript.RegisterClientScriptBlock(Page.GetType(), "hdnTotalIdScript", "var hdnTotalId = '" + hdnTotal.ClientID + "';", True)
        End If
       
       
    End Sub


Note: if it fails. Can you post your page markup?

mas_oz2003,

Thank you for helping me. Actually, this is what I'm trying to do. I modifide a user control that had the previous "RegTotal" javascript into a form that checks for the existence of a promo code, performs a discount calculation if the promo code="true" and returns an email with hdnTotal calculated.
However, when i receive the return email, the value that is calculated from the use of the variable "hdnTotalId" within 'RegTotal' is 0.00
I'll post my user control for your review below:
--------
What is happening in this code is that i do not receive the value of "hdnTotalId" that was present in the javascript code of previous version of this form
(var obj = document.getElementById(hdnTotalId);
obj.value = form.Total.value;)

Apparently, the hdnTotalID is what returns the value of the "form.Total.Value;"
This is the last piece ofthe puzzle i need to activate this form.

Can you please review?
